Mp3378e Protection Pin Upd ((link)) -

If the internal OVP of the MP3378E (e.g., 80V) is too high for your LEDs, use a resistor divider from the boost output to UPD via a Zener diode.

Shuts down the IC if the junction temperature exceeds safe limits. 2. Key Protection Pins on the MP3378E

In the television and monitor repair industry, a common diagnostic symptom is . This indicates that the MP3378E successfully completes its initial soft-start sequence, detects a faulty string or a mismatch via the VLED pins, updates the fault latch, and cuts power to the inverter circuit to prevent damage.
